With just over two weeks until Election Day, several Minnesota newspapers are endorsing the Independence Party's Tom Horner for governor.  The Star Tribune's editorial board says Horner has the best chance to overcome partisan gridlock in St. Paul.  The Forum of Fargo, the Duluth News Tribune and the Bemidji Pioneer also endorsed Horner Sunday.  Polls have shown Horner well-behind both Democrat Mark Dayton and Republican Tom Emmer.
